Title: Method and apparatus for detecting crystal orientation of substance
Inventor: MARUYAMA TAKATOSHI
IPC: H01L21/66
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for detecting the crystal orientation automatically based on the quantity of light reflected from the surface of a semiconductor wafer irradiated with light and for automating the processing line of the semiconductor wafer. SOLUTION: When the surface of a GaAs semiconductor wafer 1 is irradiated with a light 9 from a projector 2 at an angle θ1 in the range of 10 deg.<θ1<30 deg., a reflected light 10 can be detected at a predetermined angle θ2 (45 deg.<θ2<135 deg.) because the irregularities on the surface have a predetermined regularity. Crystal orientation of the GaAs semiconductor wafer is determined by a direction dependent on a position where the difference of intensity of reflected light 10 thus detected is highest, i.e., the position of a photodetector set 14 in case of the most intense reflection light 10, and a direction dependent on the position of the photodetector set 14 in case or the least intense reflection light 10.

Title: Reader for video information
Inventor: YAMAGUCHI SHINGO
IPC: H04N1/403
Filed: 1978-11-01
Abstract: PURPOSE: To perform correct binarization without malfunction, by determining threshold value through the addition of only video signal to the peak hold circuit in reading in and scanning the range of a given scanning of manuscript and a given reference voltage in other cases.  
     CONSTITUTION: The scanner 1 feeds video signal to the comparator 3, and simultaneously, the scanning position is counted, and when the part within the effective picture width is read in, the selection signal C is outputted to activate the driver D, and input is made to also the peak value hold circuit 2 via the selector switch SW. Further, if the part within the effective video width is not read in, the activation of the driver D is released and the switch SW is selected so that the circuit 2 is connected to the reference voltage generator E. The circuit 2 has the discharge circuit discharged with a given time constant and the output is divided with the divider R and fed to the comparator 3 as the threshold value S o . The comparator 3 compares the video signal with the threshold value S o  and it is picked up as the binary video signal S v , and compressed at the data compressor 4. Thus, suitable threshold value can be held and correct binary signal is always obtained.

Title: Color copying machine
Inventor: TERADA HIROSHI
IPC: G03G15/01
Filed: 1983-07-21
Abstract: PURPOSE:To adjust the tone of a color of a copying picture by a simple constitution without using a filter, by varying a relative quantity of a luminous flux reaching an original surface of plural light sources having a different spectrum. CONSTITUTION:A reflected light from an original surface 5 irradiated by light sources 1, 2 is reflected by a mirror 6, passes through a lens 7, reflected by a mirror 8 and forms an image on the surface of a photosensitive drum 9. In this case, the image formed on the photosensitive drum 9 becomes an image of a color corresponding to a light emitting spectrum of the light sources 1, 2 and a reflection characteristic of the original surface 5. In a standard position of a knob 12 of a light quantity controller, a radiation illuminance on the original surface by the light sources 1, 2 becomes a characteristic curve 15, and when the knob 12 is turned to the R side, an input to the light source from the light source 1 becomes large relatively, and the radiation illuminance of the original surface becomes a characteristic curve 16. In this case, an image formed on the photosensitive drum 9 becomes an image whose red tint is more than that of a standard case, and a red tint can be increased on a copy picture. When the knob 12 is turned in reverse, a cyan tint can be increased comparing with a standard case.

Abstract: PURPOSE:To improve light generation efficiency by a method wherein sides of a light emitting semiconductor substrate having p-n junction are beveled partially with respect to one of the main surface on the side to which the substrate supporter is adhered. CONSTITUTION:An n type and a p type epitaxial layers 12, 13 are formed on an n type semiconductor substrate 11 with an electrode for the p type layer 14 and an electrode for the n type layer 15 provided. Each side of the diode body is beveled partially 17, in other words, part of the side is angled 17 instead of at right angle with respect to the reversed surface 16 on which the electrode for the n type layer 15 is formed. Normal light rays emitted are reflected at the reversed surface 16 but the reflected rays A will not reflect at the sides so that less light rays are absorbed into the crystal. Therefore, part of light rays A which reflect from the reversed surface and emanate at approximately right angle to the beveled sides 17 can be emitted without loss.
